We studied the isothermal hydrogen adsorption and reaction at the carbon and platinum (Pt) surface of the humidified E-TEK electrode of a polymer electrolyte fuel cell (PEMFC) with a Nafion ยฎ 117 membrane by impedance spectroscopy at 30 and 50 โข C. We found three rate-limiting steps, one of them is

## Abstract The effects of ozone at concentrations near 1000โvppm in air on the performance of a single polymer electrolyte membrane fuel cell (PEMFC) were investigated. Ozone was injected to the cathode alternately with far longer operation periods at 0.54โAโcm^โ2^ with ozoneโfree air. Impedance s
The performance of Polymer Electrolyte Membrane fuel cells depends on the design of the cell as well as the operating conditions. The design of the cell influences the complex interaction of activation effects, ohmic losses, and transport limitations, which in turn determines the local current densi
